Genesis 29:20-27

So Jacob worked seven years to pay for Rachel. But his love for her was so strong that it seemed to him but a few days. Finally, the time came for him to marry her. “I have fulfilled my agreement,” Jacob said to Laban. “Now give me my wife so I can sleep with her.” So Laban invited everyone in the neighborhood and prepared a wedding feast. But that night, when it was dark, Laban took Leah to Jacob, and he slept with her. (Laban had given Leah a servant, Zilpah, to be her maid.) But when Jacob woke up in the morning—it was Leah! “What have you done to me?” Jacob raged at Laban. “I worked seven years for Rachel! Why have you tricked me?” “It’s not our custom here to marry off a younger daughter ahead of the firstborn,” Laban replied. “But wait until the bridal week is over; then we’ll give you Rachel, too—provided you promise to work another seven years for me.”
